Hager | RCBO 16A 2 Pole 6kA 30mA | DIN Rail Mount
The Hager ADA916T is a 16 amp 2 pole RCD/MCB combined in a single device (RCBO) rated 6kA, protecting against both overload and earth leakage on 30mA. It combines residual current protection and miniature circuit breaker functionality in one DIN-rail module, complies with AS/NZS 61009-1, and is suitable for commercial and residential single-phase circuits protecting motors, appliances, and control equipment.
On domestic sites and multi-unit installations, single RCBOs are often the choice over separate RCDs and MCBs because they save switchboard space and simplify labelling. The 16A rating suits general-purpose loads like lighting and power circuits on a single phase. Where a 30mA RCD is required under Australian Standards for circuits serving hand-held tools or outdoor work, the ADA916T delivers that protection in a compact 2-module footprint without wasting space on the board.
Electricians select the ADA916T for retrofit work and new installations where reliable earth-leakage tripping on 30mA is non-negotiable. The C-curve characteristic handles mild inrush currents on small motors and transformers without nuisance trips. The test button allows the installer to verify the earth-leakage function before energising the circuit, a mandatory check under AS/NZS 3017. The ADA916T has been a workhorse on Australian job sites for two decades, and the combination of affordable pricing, proven reliability, and fast availability keeps it a default choice for sparkies stocking a broad range of protection sizes.
Features
- 16A rated current — protects general-purpose circuits on a single phase, typically lighting and power subcircuits in domestic homes and commercial installations.
- Combined RCD and MCB in one device — merges earth-leakage protection (30mA) and overload protection into a single 2-module DIN-rail unit, saving switchboard space.
- 6kA breaking capacity — capable of interrupting short circuits up to 6kA, sufficient for most domestic and light commercial applications.
- 30mA earth-leakage sensitivity (Type A) — trips within 200ms if a fault current of 30mA or greater is detected to earth, complying with AS/NZS 3000 for circuits feeding power tools and outdoor equipment.
- C-curve characteristic — designed to withstand brief inrush currents from small motors and transformers (5–10 times rated current) without false tripping, while still responding instantly to true overloads.
- Test button on front — allows the installer to verify earth-leakage function in 200ms or less, a mandatory test on every RCD/RCBO installation under AS/NZS 3017.
- Manual reset after tripping — requires deliberate switch operation to restore power after a trip, preventing automatic reconnection if a fault persists.
- Right-hand neutral position — designed for standard left-to-right switchboard layouts on DIN rail, with the neutral (N) terminal on the right.
- Wide temperature tolerance — rated to operate safely from -25°C to +40°C without derating the 16A current, ensuring reliable performance across Australian climate zones.
- DIN-rail mounting — standard snap-on top and screw-down bottom clips; removable from the bottom rail without tools for easy replacement.
Where to use
- Domestic circuits feeding hand-held power tools — AS/NZS 3000 mandates a 30mA RCD on any circuit supplying portable tools; the ADA916T in a subboard delivers both protection and switchboard space savings.
- Rental properties and granny flat wiring — common requirement in multiunit installations where each tenancy needs independent circuit protection; the compact RCBO reduces the number of modules on the main board.
- New build and renovation switchboards — general-purpose protection on lighting and power subcircuits serving kitchens, lounges, bedrooms, and hallways.
- Retrofit upgrades to older installations — when replacing a failed separate RCD and MCB pair, the ADA916T fits in the same space and simplifies the switchboard diagram.
- Industrial control circuits — protecting 240V single-phase motors, solenoid coils, and smaller transformers on portable control gear or machinery with integrated switchboards.
- Caravan and site van electrical systems — where space is tight and a 30mA-sensitive RCBO is required by standard, the compact ADA916T is the single-module choice.
The ADA916T is not suitable for circuits where harmonic currents or DC-leakage ground faults are likely to occur (for which Type B or Type F RCBOs are required). It is also not designed for AC or DC leakage types beyond Type A residual currents, and should not be used in situations where 100mA or larger leakage sensitivity is required by design.
